Mexican officials say they are expecting DNA results at the earliest on Monday in connection with the death of Monica Beresford-Redman, wife of Survivor producer Bruce Beresford-Redman, RadarOnline.com has learned exclusively.

The 41-year-old was found in a sewer outside the luxury hotel Moon Palace in Cancun, Mexico, where she was vacationing with her husband Bruce, who in addition to Survivor, worked on Pimp My Ride. Bruce was arrested April 8 and later released, but is not allowed to leave the country pending the investigation. State investigator spokesman Adrian Cardana told RadarOnline.com that Bruce is the only suspect in the case and is under the care of the U.S. Consulate.

Monica’s family said that Bruce was having an affair, and the couple went to Mexico to rekindle their marriage. Monica’s sister, Carla Burgos, told RadarOnline.com exclusively: “There were witnesses who heard someone screaming and calling for help,” in the swanky hotel. Cardana tells RadarOnline.com that there were no security cameras in that part of the resort. Several hotel employees were reportedly interviewed by Mexican investigators on Wednesday and generally agree on the events of that night. But details were not released.

Earlier Carla had said Bruce “has scratches on his arm,” and the state investigator’s office confirms he also has scratches on his body. The autopsy report released Thursday says Monica died from asphyxiation and suffocation.

DNA samples were taken from the crime scene and from the victim’s body, according to Cardana, and tests are underway. When Bruce was detained DNA samples were also taken from him and the results may be released on Monday.

Investigators say the only thing standing in the way of an arrest now is the DNA results. Cardana says the information they get from the DNA results will be the determining factor for the possibility of extradition.

Bruce and Monica have two children, who are now in the custody of Bruce’s parents.
